Making your own lavender soap is not only fun, it is also a great and thoughtful idea as a gift. Lavender Soaps are very calming and aromatic and I am going to teach you how to make lavender soap 3 ways. The easy way is the melt and pour method which is as you might have guessed as simple as melting the soap base here and pouring it into molds. The second method is the cold process and the last method is the hot process.

What are the main differences between hot and cold process?

The main difference between the hot and cold process is using heat vs not using any heat, the time it takes to saponify, curing time and the finish of the soap.


  • The saponification in the cold process takes longer, about 24 hours to complete. In the hot process, it takes about 2 hours.

Cure Time

  • The cure time (meaning the time you need to let the soap become soap and ready to use) can take up to 4 weeks for the cold process. For the hot process, only 1 week is needed.

    Final results

  • The cold process has a more smooth result so if you are patient it will pay off!

Method 1: Melt and Pour Lavender Soap

How to make lavender soap with melt and pour is the easiest method that you can use in creating your own organic lavender soap. This is because all we ever need to do is use a pre-made soap base, add your very own magic, and slather away!

Why use melt and pour soap?

It’s quick and easy. This is perfect for those who are busy and who want to make their own lavender soap fast. The base is already pre-made and you don’t have to deal with lye! It’s similar to having a quick-mix versus starting from scratch when you are trying to bake a cake.

Why do I need Lye to make soap?

Lye is the ingredient needed for soap making that causes a chemical reaction called saponification. It is a caustic liquid that is corrosive and can cause burning if it comes in touches the skin. Lye fumes can be very annoying too and if you make soap in an apartment, make sure you open the windows as the fumes can be irritating. Also, since you don’t have to deal with lye with the melt and pour method, you don’t really need to wear goggles.

What is a melt and soup base?

A Melt and Pour soap base is like skipping some steps in the hot process because we already have the base pre-made.  It combines the base oils and lye solution. Basically, the hard part is done for us!

What are the skin properties of lavender essential oil?

Not only lavender smell divine but lavender essential oil has many known benefits in skin care on top of being a natural soothing and calming ingredient. It has antiseptic, anti-inflammatory and antidepressant properties. It soothes your mood, your skin, body, and soul!

How to give your soap a purple color?

Thankfully, there are natural ingredients that can be used as colorants instead of chemical dyes. For the purple color in lavender soap, I use Alkanet root powder.

What is Alkanet Root Powder?

Alkanet root powder is primarily used as a natural dying color with purple hues. In the past, it has been made as a natural agent to improve the color of poor quality wines, but are now primarily used on skincare and cosmetics such as soaps and lip balms. it comes from a herb in the borage family with beautiful bright electric blue flowers. The root has been used as a dye in the Mediterranean region since antiquity.

In soap, Alkanet root will yield shades of pink, blue, and purple, depending upon the amount used, types of oil used, and the alkalinity of the soap.

Method 2: Lavender Soap Cold Process

It can cost you more time than the melt and pour process because of cure time needed, but it’s a great way to make soap from scratch if you have the patience!

Here are the ingredients you will need for a lavender soap cold process:

Liquid & Lye Portion:

  • 4.01 ounces lye (6% superfat)
  • 9 ounces lavender tea (or distilled water)

Wearing proper safety gear (gloves, goggles, long sleeves), carefully measure, pour, and stir the lye (sodium hydroxide) into the cooled lavender tea. I work in my kitchen sink, to contain any spills. Let this cool to around 90 to 115 degrees Fahrenheit.

Oil Portion (29 ounces total):

Method 3: Lavender Soap Hot Process

What is soap hot process? This is somewhat similar to cold-processing in a sense that it also allows you to combine all your preferred oils and essences, but this method doesn’t have a long cure time and the resulting soap can be readily used as it hardens.
